An idempotent is a matrix whose square is itself. Specifically, A^{2}=A. For example the 2x2 matrix

A= 1 1

0 0

is idempotent.

A square matrix A is idempotent if A^2 = A. It's really simple

yes,the histogram equalization operation is idempotent

An idempotent matrix is a matrix which gives the same matrix if we multiply with the same.

in simple words,square of the matrix is equal to the same matrix.

if M is our matrix,then

MM=M.

then M is a idempotent matrix.
